100% CPU usage after some time

Hello,

After upgrading to python3.9 and big Sur, it appears pyls will start consuming 100% CPU after some time. What can I do to try and figure out why?

+1 Running with the same symptoms CPU 100% after some time. But python 3.8 and Linux.

If you have some direction to try to figure out what happen and which information can be useful please ask.

I didn't find anything, my language server setup is properly broken for python. I'm just waiting for neovim 5.0 at this point which has a language server built in.

It is likely due to an outdated Jedi package.

it appears the latest version of python-language-server still doesn't support the next version of jedi (the setup.py says < 0.18.0)
